Why pixel-based attribution broke
Opt-outs, capped attribution windows, and cookie loss mean pixels now miss and misattribute a large share of conversions. Patching them with modeled conversions inside each platform just re-introduces the platform's bias.
The first-party alternative
Your Shopify orders and GA4 exports are first-party and complete. Causal modeling on that history estimates each channel's incremental contribution without tracking individual users - privacy-safe by construction, and unaffected by the next browser change.
Find your wasted ad spend in 5–10 minutes.
Watch the model work on a sample store first, no signup. Then upload your last 40–90 days of GA4 sessions and get incremental ROAS with confidence intervals. No pixel, no SDK. €99 per read.
